" A PEDAL ASSEMBLY TO OPTIMIZE STOPPING DISTANCE IN
SADDLE TYPE VEHICLE"

FIELD OF INVENTION
The present invention relates to a pedal assembly and more particularly to a pedal assembly to optimize stopping distance in saddle type vehicle.
BACKGROUND OF THE INVENTION
[0001] In the recent years, a combined braking system (hereafter referred as CBS) has become need of the two wheelers, that also contributes for the safety of a rider. In CBS both the front and rear wheel brakes are applied simultaneously or synchronously, hence it reduces stopping distance of vehicle after application of brake and in turn reduces skidding and possibility of accidents in non CBS vehicles. According to the government guidelines and as per IS 14664-2010, now it is mandatory to implement combined braking system in two wheelers below 125 CC capacity.
[0002] From past few years many developments are being carried out in CBS.
Broadly, CBS may be implemented with hand operated lever mechanism for scooters or pedal operated mechanism in motor cycles or combination of both.
[0003] In conventional CBS, the rear and front brakes are applied simultaneously. In panic braking incidents due to simultaneous actuation of both rear and front wheel brakes, there is a possibility of wheel locking, that may lead to loss of control or skidding of a scooter or motorcycle.
[0004] The conventional CBS, includes more number of moving elements
which induces frictional force which results in reduced life of the components also causes complication in the spares replacement. Further, the conventional combined braking system is very complex in design and expensive.
[0005] To improve safety of the riders CBS with delay mechanism had also
been disclosed in the prior art. In CBS with a delay mechanism, on the actuation of the pedal or the lever the rear brake is applied immediately, whereas a front brake is applied after predefined delay. In conventional CBS this delay is fixed.

[0006] Many of the CBS in the prior art had reported the use of equalizer
assembly that enables the desired load distribution between front wheel and rear wheel brakes. Typically, this load distribution ratio is 60:40 between rear wheel brake and front wheel brake respectively and that is also fixed.
[0007] Although, the conventional combined braking systems have been
proved to be an advantageous, there is still a scope to improve the functionality and performance of the braking system. In case of accidental damage of the CBS system may affect safety of the rider due to interdependent load transfer mechanism in conventional CBS.
[0008] Hence there is a need of a pedal assembly for saddle type vehicle that
ensures safety of a rider by means of separate load transfer mechanism along with variable delay and variable load distribution between front wheel and rear wheel brakes of saddle type vehicle, that also provides ease in spare parts replacement.

[00027] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[00028] An aspect of the present invention pertains to a pedal assembly for saddle type vehicle with separate load transfer and variable load distribution mechanism. Fig. 1 shows a front perspective view of a pedal assembly for saddle type vehicle in the preferred embodiments of the present invention. The pedal assembly (100) includes a pedal body (110), a bracket (120), a cam lever (130), a front holder (140), a spring (150) and a rear holder (160).
[00029] Now referring to Fig. 2A, Fig. 2B and Fig. 3 collectively, the pedal body (110) further includes a foot pad (110A), a pedal lever adaptor (HOB) and a protrusion 110C). The pedal body (110) is operated with respect to a first pivot (PI). The pedal lever adaptor is hingedly connected with the rear holder (160) that is connected to a rear brake rod (240). The front holder (140) receives a front brake cable (230) to enable actuation of front wheel brake.
[00030] The cam lever (130) in accordance with the preferred embodiment of the present invention having a proximal end (130A), a distal end (130B), a first pivot hole (130C), a proximal edge (310) and a distal edge (320). The protrusion (HOC) of the pedal body (110) has at least one groove to accommodate the proximal edge (310) of the cam lever (130).
[00031] The bracket (120) includes a second pivot hole (120A) and adapted to support the cam lever assembly. The cam lever (130) is pivotably mounted on the bracket (120) at a second pivot (P2) by means of the first pivot hole (130C) and the second pivot hole (120A) that are coaxially aligned to receive a pivot pin (220A) along with the spring (150).

[00032] The cam lever (130) is mounted on the bracket (120) at the second pivot P2 such that the proximal edge (310) is abutted against the groove of the protrusion (HOC) and the distal end (130B) of the cam lever (130) is fastened with the front holder (140).
[00033] A spring (150) having predefined stiffness that is coaxially mounted on the pivot pin (220A) at the second pivot P2. The spring (150) is configured to provide predefined delay and to keep the proximal edge (310) of the cam lever (130) abutted against the groove of the protrusion (HOC), wherein a first end (150A) and a second end (150 B) of the spring (150) are engaged in a cam hole (BOD) of the cam lever (130) and a bracket hole (120B) respectively.
[00034] Now referring to Fig. 1 through 3, the operational characteristics of pedal assembly (100) for saddle type vehicle with separate load transfer mechanism to improve safety of the rider is explained. When the foot pad (110A) is pressed, the pedal lever adaptor (HOB) fluctuates from the first pivot (PI) and causes pulling of a rear rod (240) through rear holder (160) to actuate rear wheel brake. The pressing of the foot pad (110A) also causes displacement of the protrusion (HOC) and cam lever (130), as the proximal edge (310) of cam lever (130) is abutted against the groove of the protrusion (HOC). After predefined delay that is defined by the stiffness of the spring (150), the proximal end (130A) of the cam lever (130) starts rotating in the direction of braking force received from the protrusion (HOC) due to pressing of the foot pad (110A). In proportion to the displacement of the proximal end (130A), the distal end (130B) of the cam lever (130) also starts rotating with respect to the second pivot (P2) in the similar direction of rotation as that of proximal end (130A). As the distal end (130B) is fastened to the front holder (140) that receives the front brake cable (230), the front brake cable gets pulled to actuate front wheel brake.
[00035] The arrangement of the protrusion (HOC) and the cam lever (130) is adapted to optimize stopping distance of the vehicle with separate load transfer mechanism between front and rear wheel brakes. This feature enhances safety and

reliability feature of the braking system. The said assembly also provides variable delay and variable load distribution between front and rear brakes of the saddle type vehicle. The said invention also improves efficiency and overall performance of the system due to reduction in number of movable parts.
